DISPOSITIF ET PROCEDE DE PURIFICATION D'HYDROGENE PAR ADSORPTION

摘要

The invention concerns a vehicle power module consisting of a fuel cell having at least one anode compartment and at least one cathode compartment, a reforming reactor, at least one purification column (20) having a reversible adsorbent (29) and receiving a hydrogen-containing gas mixture from the reactor and supplying a hydrogen-rich gas to the anode compartment, wherein the column (20) is supplied with a gas mixture through a first inlet and with a desorbent through a second inlet separate from the first inlet, and the thermal insulation of the walls of the purification column (20) is different on the first inlet side and on the second inlet side
